C65 Divetimer Special Edition
A watch is the most convenient and beautiful way of telling the time.
But when you’re exploring the ocean depths, it has to be much more
than that. Hundreds of meters under the surface, reliability and
accuracy are matters of life and death.
And that’s the provenance behind your C65 Divetimer Special Edition.
As you’ll be aware, the dial carries a decompression scale to help you
calculate decompression stops as you ascend from a deep dive.
And while we wouldn’t advise using it when you’re underwater,
it’s a brilliant planning tool – with a remarkable history.
Decompression scales appeared on watches in 1962 when Dr Hannes
Keller – physicist, mathematician and extreme diver – attempted the
world deep-sea dive record. Not only did he require a watch to keep
track of his time underwater, but he also needed a decompression
table that let him calculate how long his stops had to be.
The result was a watch, made by Vulcain, that had a decompression
scale printed on the dial. And that scale is now found on the face
of your C65 Divetimer Special Edition.
While you might not spend your leisure time exploring, say, the
Pacic’s mega-deep Mariana Trench, it’s good to know that if you
did, you’d be able to do so with condence. And in style.

How to operate your C65 Divetimer Special Edition
Setting the time
For a superior water resistance your crown is of the screw-down
type. The crown should sit ush to the case (position 1) in order
to maintain water resistance.
• First unscrew the crown anti-clockwise from the case to position
2for winding in power. Wind in a clockwise direction to re-power
the watch. Your C65 Divetimer Special Edition has a maximum
power reserve of 42 hours when fully wound.
• Pull gently into position 3. This position is used for handsetting
and stopping of the seconds hand. For precise time setting it is
recommended to pass beyond the desired minute and to set the
hand backwards.

How to operate your C65 Divetimer Special Edition
If using the bezel for a dive and let’s say the recognised maximum
“no-stop time” is 55 minutes, then in this example (shown right)
the time at the surface immediately before the dive is 10.08am.
However the bezel marker is at the 12.00 hr position.
• Move the bezel marker anti-clockwise so that it aligns with the
8 minute position.
• You can now read that the 55 minute no decompression limit
will occur at 3 minutes past the next hour.
Diving with your watch
How to use your watch’s decompression scale
A decompression scale is a reference tool for divers to consult before
they take to the water. It enables you to work out how long your
decompression stops should be – depending on how far down you’ll
go and how long you’ll stay there.
Say you’re planning on diving at 30m for 35 minutes. Go to the
concentric ring with ‘30/95’ printed at the top and follow it around
until you hit the 35-minute index on the ‘regular’ part of the dial.
You can see that your decompression stop should be 15 minutes.
You’ll also notice some circular orange bands. These tell you the
no decompression limit for each depth. If you choose to dive
to 25m/80ft, the orange band goes to the 35-minute mark on the
dial, which is how long you can dive at this depth without taking
a decompression break.

Start of dive
PLEASE NOTE:
It is always useful and best practice to make a note on a
dive slate before entering the water and to carry a set of dive
tables should the dive plan change during the course of a
dive. A safety stop for 3 to 5 minutes at 15ft is recommended
at the end of all dives. A safety stop for 3 minutes at 15ft
is required any time you come within 3 pressure groups of
a no decompression limit, and for any dive to a depth of
100ft or deeper.
